LUTHER C. CROWELL, OF BROOKLYN, ASSIGNOR TO B. HOE & 00., OF NEW YORK,N. Y.

SHEET-DELlVERY M ECHANlSM.

SPECIFICATION forming part of Letters Patent No. 339,531, dated April 6,1886.

Application filed March 28, 1885.

To all whmn it may concern:

Be it known that I, LUTHER C. CaownLL, a citizen of the United States,residing at Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful Improvements in Sheet-DeliveryMechanism, fully described and represented in the followingspecification,and the accompanying drawings,forming a part of the same.

This invention relates, generally, to that class of delivery mechanismwhich is adapted to operate upon a printed web to sever the same intoshort lengths or sheets, and fold and de liver said sheets in properform for distribution as newspapers.

It is the object of the invention to provide a mechanism of thischaracter which is capacitated to deliver products of different size orvolume, so as to meet the wants of those publishers who desire to issuepapers which vary in size with the different days of the week, and alsoto deliver the product folded to diii'erent dimensions, so as to be insuitable form for distribution, either by carriers or by mail.

The invention relates particularly to the means by which the mechanismis capacitated to deliver the product folded to different dimensions.

The details in the construction of the mechanism in which the inventionis embodied, and also its organization and operation,\vill behereinafter so fully described and explained as to render all furtherpreliminary description unnecessary to a complete understanding of theinvention.

In the accompanying drawings, Figure 1 is an elevation of a deliverymechanism embodying the present invention. Fig. 2 is a similar viewlooking from the right of Fig. 1. Fig. 3 is a plamview of a portion ofthe mechanism, showing the web turners around which the sections of theweb pass to be di rected to the folding mechanism. Fig. 4 is a similarview of the whole mechanism, the webturners,the frame in which they aremounted, and the brackets upon which this frame is supported beingremoved. Fig. 5 is a sectional elevation taken upon the linear of Figs.1 and 4, the web-turners and the frame in which Serial No. 160,436. (Nomodel.)

they are mounted being omitted. Fig. 6 is a sectional elevation takenupon the line 3/ y of the same figures, the web-turners and frame inwhich they are mounted being omitted and the folders of the primaryfolding mechanism shown as adjusted to a different position. Fig. 7 isan irregular cross-section of the machine,the sheet-laying mechanismbeing omitted, and also the greater part of the supporting frame-work.Fig. 8 is an enlarged sectional elevation of a portion of Fig. 6. Fig. 9is adiagrammatic plan view illustrating the travel of the webs andsheets through the delivery mechanism when the parts are adjusted to theposition shown in Figs. lto 5,inelusive. Fig. 10 is a similar viewillustrating the travel of the Webs and sheets through the deliverymechanism when the parts are adjusted to the position shown in Fig. 6.Figs. 11 and 12- illustrate the condition of the product after it haspassed the primary folding mechanism. Figs. 13 and 14 illustrate thecondition of the product after it has passed the intermediate foldingmechanism. Figs. 15 and 16 illustrate the condition of the product afterit has passed the final folding mechanism when said final mechanism isadjusted to the position shown in Figs. 6 and 10; and Figs. 17 and 18illustrate the condition of the product after it has passed the finalfolding mechanism when said mechanism is adjusted to the position shownin Figs. 1 to 5 and 9.

Referring to said drawings, it is to be understood that the deliverymechanism therein shown as embodying the invention is designed tooperate in connection with a printing mechanism which perfects adouble-width web, and consists, essentially, of a primary foldingmechanism composed of two longitudinal folders, 100 101, arranged one inadvance of the other, and in such position that the webs or sheets fromboth pass between the same pair of rolls, an intermediate folding andsevering mechanism composed of a pair of folding and cutting cylinders,102 103, and a pair of folding-rolls, 104 105, arranged to receive thewebs from both of the folders of the primary mechanism, sever them intosheets,and fold the sheets transversely, a. final folding mechanismcomposed of two longitudinal folders, 106 107, arranged side by side,and in such position that each re ccives the product of one of thefolders of the primary mechanism, and a sheet laying or piling mechanismconsisting of a rotary carrier or fly, 108, which is arranged to receiveand pile the sheets from both the folders of the final foldingmechanism.

The intermediate and final folding mechanisms and the sheet-pilingmechanism are supported in a suitable frame-work, 110, which does notrequire specific description, as a frame suitable for the purpose can bedesigned and constructed by any ordinarily skillful mechanic. Theprimary folding mechanism is mounted upon a supplemental or auxiliaryframe-work, 109, which is so constructed and arranged that it can beadjusted to diiferent positions upon the frame 110, and thereby bringthe folders 100 101 into different positions with relation to the othermechanisms. The purpose of this adjustment as well as the particulardevices by which it is effected will be hereinafter fully explained.

Referring now particularly to Fig. 3, it is to be understood that theweb A, after having been perfected by any ordinary form of web-printingmechanism and split into two sections, a a, by an ordinary slitter,located at any convenient point, is letin at the side of the deliverymechanism in such position that the two sections, or, as they will behereinafter termed, webs, a a will pass above a pair web-turners, 90 91,which are arranged in the usual manner, so thatin passing around themthe two Webs are turned at right angles to their previous path of travelbefore they are presented to the folding and delivery mechanisms. Theweb-turners 90 91 are supported at their ends on a rectangular frame,99, (see Figs. 1, 2, and 3,) which rests on brackets 98 rising from theframe 110. The two pairs of brackets 98 at the ends of the frame areconnected by cross-bars 97, and the ends of the frame 99,'which restupon these bars, are provided with flanges 96, which lie upon theoutsides of the bars, and thus prevent the frame 99 from movinglengthwise. The side pieces of the frame 99 are provided at theirendswith downwardly-extending lugs 95, through which pass adjusting-screws94, the inner ends of which impinge against the brackets 98. By thismeans the frame 99 can be shifted laterally,so as to vary the positionof the web-turners with relation to the folders 100 101. The purpose ofthis will be made clear when the operation of the mechanisms isdescribed. After passing the turners 90 91 the two webs are led aroundregister-rolls 92 93, which are mounted in adjustable hearings in theframe 109 in such manner that they can be shifted in position and thusregulate the travel of the webs, so as to bring the printed pages intoproper register with the cutting and folding mechanisms. After passingaround the register-rolls 92 93, the webs are led rearward, as indicatedby the arrows, to rolls 88 89,

which are also journaled in the frame 109,and located just above thebases of the folders 100 101.

The folders 100 101, as herein shown, are of substantially the sameconstruction as one of the forms shown and described in United StatesLetters Patent No. 281,619, to which reference is made for a detaileddescription thereof. They are not, however, provided with tapes, asshown in the Letters Patent referred to, be cause as the folders are toact upon the webs before they are severed into sheets such tapes are notabsolutely necessary, though in some cases it will be found desirable toprovide these folders with tapes, and this can be readily done. Thesefolders are arranged one directly in advance of the other, and aresupported at their bases upon transverse bars 86 87, which are securedto the sides of the frame 109, and at their points by means of pivotedrods 84 85, which pass through brackets 83, extending downward from thesides of the frame, and are provided with adj usting-nuts 10, by whichthe'points of the folders can be adjusted so as to be brought intoproper position with relation to the bite of the rolls 81 82, whichconstitute the external turners of the folders.

The frame 109, in which the folders 100 101 constituting the primaryfolding mechanism are supported, is, as before stated, made adjustablewith relation to the frame 110, in which the other parts of themechanism are supported, so as to permit these folders to be broughtinto different positions with relation to the subsequent foldingmechanisms. For this pun pose the sides of the frame 109 are providedwith flanges 80, which rest in bearings 79, formed in the upper part ofthe sides of the frame 110, while the brackets 83, which connect theside pieces of the frame 109, are provided at their bottoms withbearings 78,which rest upon beams 77, extending from one end to theother of the frame 110, as best shown in Figs. 1, 4, 5, and 7.

To effect the proper adjustment of the frame 109, the rearmost oneof thebrackets 83 is provided with a nut, 76, in which works a screw-rod, 75,which is journaled in the end of the frame 110, and is provided with ahandwheel, 74, by which it can be operated so as to move the frame 109along the beams 77 and bearings 79, and thus shift the position of thefolders. The rolls 80 81, which constitute the external turners ofthefolders 101, are, as will be observed, journaled in the frame 110,and are of sufficient length to always cooperate with the folders, nomatter into what position they are adjusted, by the movement of theframe 109. After passing around the rolls 88 89, the webs are leddownward across the faces of the folders 100 101, and between the rolls81 82, so that each is folded longitudinally. After leaving the rolls 8182 the two webs, now folded longitudinally, are led side by side to thecutting and folding cylinders 102 103 of the intermediate foldingmechanism. The cylinder 103, which is of a circumference equal to thelength of one sheet, is l the arrangement of which will now bedeprovided with the usual severing-blade, 11, while the cylinder 102,which is of a circunr ference equal to the length of two sheets, isprovided with two co-operating cutting-grooves, 12. Just in the rear ofthe grooves 12 the cylinder 102 is provided with two sets ofinipaling-pins, 13, which are arranged to be moved in and out throughopenings in the cylinder, and are mounted upon arms extending from rockshafts 14, which are jou rnaled in the heads of the cylinder, and areprovided with rockarms 15. (see Fig. 5,) which are operated by astationary cam, 16, so as to protrude and retract the pins to impale andrelease the sheets at the proper times, the arms 15 being held to thecam 16 by means of springs, (not shown,) which are arranged in the usualmanner.

At the proper points between the cuttinggrooves 12 the cylinder 102 isprovided with two rotating folding-blades, 17, which are of the commonconstruction, and are mounted upon shafts 18, journaled in the heads ofthe cylinder and operated to fold the sheets off the cylinder at theproper times by means of cross-heads 19, which engage with a stationarycam, 20, and operate the blades in the usual manner. The folding-rolls104 105, which co-operate with the cylinder 102 and blades 17, are alsoof the common form, and are arranged in the usual position with relationto the cylinder. After leaving the rolls 104: 105 the two webs, nowsevered into sheets, pass into the control of a series of tapes, 9,which pass around the roll 10!: and a roll, 73, located a short distancein advance of the foldingrolls, and by which they are directed betweentwo series of guides, 21 22, and into the bite of tapes, by which theyare conveyed to the folders 106 107 of the final folding mechanism, andthence to the piling mechanism.

The folders 106 107, which constitute the final folding mechanism, areof substantially the same construction as the folders 100 101 of theprimary folding mechanism, except that they are smaller in size and haveone of their turning edges extended or elongated considerably beyond theother. The purpose of this elongation of one of the turning edges willbe made'clear when the operation of the mechanism is explained. Thesefolders. instead of being arranged one in advance of the other, so thatboth co-operate with the same pair of rolls, as is the case with theprimary folders, are arranged side by side an d provided with separatepairs of cooperating rolls or external turners. It will be observed thatas the webs have been severed into sheets before arriving at thesefolders it becomes necessary that they should be provided with tapes forconducting the sheets over them, and, as here shown, the tapes whichoperate to conduct the sheets to and over the folders of the finalmechanism are so arranged that they also conduct thesheets from thesefolders to the piling mechanism. The tapes by which this is accomplishedconsist of six series, 2 3 4: 5 6 7,

scribed. The series 2, 4, 3, and 7 pass around pulleys 23, located justabove and at the ends of the guides 21 22, thence upward around pulleys24, located at the bases of the folders. From this point the tapes 2pass downward across the face of the folder 106 and around the longer ofits turning edges, and thence inward between the rolls 71 72, which formthe external turners of this folder. From the pulleys 24 the tapes 4pass downward across the face of the folder 106 and around its oppositeor shortertnrning edge, and thence inward between the rolls 71 72,wherethey unite with the tapes 2. From the rolls 71 72 the two series 4pass beneath pulleys 25, and thence between pulleys 26 27, at whichpoint they separate, the tapes 2 passing around pulleys 28, thence aboveand for a short distance in contact with the cylinderfly 108, thencebeneath pulleys 29, and outward around pulleys 30, thence upward aroundpulleys 31, and thence inward around skew-pulleys 32, while the tapes 4pass upward from the pulleys 27, around pulleys 33, and thence inwardaround skew-pulleys 34. From the pulleys 24 the tapes 3 pass downwardacross the face of the folder 107 and around its longer turning edge,and thence inward between the rolls 69 70, which constitute the externalturners of this folder, while the tapesb pass downward from the pulleys24, acrossthe face of the folder and around its opposite orshorterturning edge,and thence inward between the rolls 69 70, where they unitewith the tapes 3. From the rolls 69 70 both series of tapes pass beneathpulleys and thence between pulleys 36 37, where they separate, theseries 5 passing beneath the pulleys 28, around the cylinder-fly, andthence outward around pulleys 38 and upward around pulleys 39, andthence inward around skewpulleys 40, while the series 3 pass upwardaround the pulleys 37, thence around pulleys 41,-and inward aroundskew-pulleys42. From the skew-pulleys 32 34 40 42 all of the tapes passrearward around pulleys 43 and return to the pulleys 23. The tapes 6 7pass around pulleys 44, located directly beneath the pulleys 23, thenceupward past the pulleys 23, and around the pulleys 24, thence downwardaround pulleys 45, located at different points along the converginginnersides of the turning edges of the folders, returning aroundstretchingpulleys 46 to the pulleys 14.. The spaces between the pulleys27 37 and the pulleys 28 are bridged by stationary guides 8,(see Fig.8,) which cooperatewith the tapes 25 to convey the sheets from theformer to the latter pulleys,while the spaces between the turn ing edgesof the folders and the rolls 71 72 and 69 70 are bridged by stationaryguides 47,(see Figs. 4. and 7,) which co-operate with the tapes 2- at 35, to convey the sheets from the turning edges of the folders to saidrolls.

he cylindenfly 108 is so positioned with relation to the rolls 71 72 and69 70 that the distance traveled by the sheets issuing from between eachpair of these rolls before they arrive upon the surface of the fly willbe the same, from which it results that the sheets from the two folders106 107 arrive at the fly at the same time, and thus became associatedin pairs as they are taken by the fly, as indicated in Fig. 8. By thismeans a simple fly is enabled to pile the product of both folderswithout operating at any greater speed than would be necessary in pilingthe product ofa single folder.

The fly 108, as here shown, is of the same or substantially the sameconstruction as that shown in United States Letters Patent No. 281,754,and in my application for Letters Patent filed October 23, 1884, No.146,256, and consequently needs no specilicdescription. It is providedwith three sets of grippers, 48, which are operated by a stationary cam,49, to take and release the sheets at the proper time, and withco-operating-stops 50, and a slowly-moving apron or series of tapes, 51,by which the sheets are arrested as they are released by the grippers 48and conveyed away from the fly.

As illustrated in the present case, the various parts of the deliverymechanism just described receive motion as follows: The cylinders 102103 are connected by gears 52 53, (see Figs. 9 and 10,) and the shaft ofthe cylinder 102 is provided with a gear, 54, (see Fig. 5,) whichengages with a gear, 55, upon the shaft of the roll 81, the rolls 81 82being geared together in the usual manner. The shaft of the cylinder 102is also provided with a gear, 56,which is connected throughintermediates 57 58 with a gear, 59, upon the shaft of the pulleys 44,which gear 59 in turn engages with a gear, 60, upon the shaft of thepulleys 23. The gears 56 57 58 are so proportioned that the speed of thetapes 2 3 4 5 6 7, which are driven by the pulleys 23 44:,wil1 begreatly reduced from that of the cylinders 102 103, thus allowing thesheets after they have been folded transversely, and consequentlyreduced one-half in length, to have their speed reduced during theirpassage through the final folding mechanism and to the piling mechanism.The gear 57 also engages with a gear, 61, which is mounted upon a shaft,62, which is provided with a bevel-gear, 63, which engages with asimilar gear, 64:, mounted upon the shaft of the cylinder-fly 108, andthe shaft of the fly 108 is also provided with a gear, 65, which engageswith a gear, 66, mounted upon the shaft of the pulleys 28. The rolls 7172 and 69 70 are geared together in the usual manner, but are driven bythe tapes 2 4 and 3 5. This particu- 'lar arrangement of the gears forcommunicating motion to the various parts is not, however, essential,and may be varied according to circumstances. The tapes 51 may be drivenby connections with any one of the moving parts. The power may beapplied at any convenient point, but will preferably be applied to theshaft of the cylinder 103.

The delivery mechanism hereinbefore described is capacitated to deliverthe following products folded to the following dimensions, viz: aproduct consisting of one full sheet folded .once transversely and twicelongitudinally, or once transversely and once longitudinally; or aproduct consisting of two full sheets associated together and foldedonce transversely and twice longitudinally, or once transversely andonce longitudinally. The operation of the mechanism in delivering theseproducts is as follows:

When it is desired to deliver aproduct consisting of one full sheetfolded once transversely and twice longitudinally, the, frame109,carrying the rolls 92 88 and 93 89, and the folders 100 101 of theprimary folding mechanism will be shifted by means of the screw 75, soas to bring the folders into the position shown in Fig. 6, and indicatedin the diagram Fig. 10. The web A, after being perfected by any suitableform of web-printing mechanism and split into the two sect-ions ornarrow webs a, a", will beled in at the side of the delivery mechanism.as shown in Fig. 3. The web a will then be led around the turning bar90, and thence around the rolls 92 88 and downward over the folders 100,and between the rolls 81 82, while the web a will be led around theturning-bar 91and thence around the rolls 93 89, and downward over thefolder 101, and between the rolls 81 82, as shown in Figs. 4 and 6. andbetween the rolls 81 82, the webs will be folded longitudinally, asshown in Figs. 5and 10, and in this condition they will be led side byside between the cutting and folding cylinders 102 103, as shown in Fig.1, where their leading ends will be impaled by oneset of the pins 13, soas to be carried around upon the surface of the cylinder 102. When thecylinder 102 has completed one-halfof arevolution the blade 11, coactingwith one of the grooves 12, will sever the webs, thus leaving a pair offull sheets foldedto the form shown in Figs. 11 and 12 impaled upon thepins, and at the same time the other set of pins, 13, will impale thenewly-cut ends of the web, so as to carry them around upon the cylinder102. The pair of sheets just severed from the webs will be retained bythe pins and carried around upon the cylinder until the folding -blade17, in the rear of the pins upon which the sheets are held, comes intoposition to coact with the rolls 104 105, when the pins will beretracted so as to release the sheets, and at the same time the blade 17will be operated so as to fold them off the cylinder and into the biteof the rolls, as shown in Fig. 1. At the end of the next half revolutionof the cylinder 102 the blade 13, coacting with the other of the grooves12, will sever another pair of sheets from the webs, which sheets Inpassing over the folders 100 101' versely, and in the form shown inFigs. 13 and 14, will be directed by the tapes 9 between the guides 2122, and into the bite of the tapes 2 1 6 and 3 5 7 respectively. Thesheets will then be carried upward by these tapes over the pulleys 24,and thence downward over the folders 106 107, and between the rolls 7172 and 69 70, as shown in Figs. 6 and 10.

It will be observed that when the folders 100 101 are in the positionshown in Fig. 6, and indicated in Fig. 10, the webs will be delivered tothe cylinder 102 in such position lengthwise of the cylinder that thesheets severed from the webs will be carried by the tapes onto thefolders 106 107 in such position that their center lines will passdirectly over the points of the folders. In passing over the folders 106107, and between the rolls 71 72 and 69 70, the sheets will receive asecond longitudinal fold, which will reduce them to the dimensions shownin Figs. 15 and 16. After leaving the rolls 71 72 and 69 the sheets willpass into the control of the tapes 2 4. and 3 5, by which they will becarried forward until they have passed the guides 8, when they willbeassociated together and pass into the control of the tapes 2 5, by whichthey will be conducted onto the cylinder-fly 108, as shown in Figs. 6and 8. As the leading ends of the pair ofsheets arrive in proporposition upon the fly 108, they will be taken by one of the sets ofgrippers 48 and carried around upon the fly until they arrive at or nearthe stops 50, when they will be released by the grippers and allowed tofall onto the tapes 51, as shown in Figs. 6 and 8, to be conveyed awayfrom the machine.

If it is desired to deliver a product consisting of two full sheetsassociated together and folded as just described, the folders 100101will remain in the position shown in Fig. 6, and indicated in Fig. 10;but the web a, after being led around the turning-bar 91 instead ofbeing led around the rollers 93 89 and over the folder 101, will be ledforward over the roller 68, and onto the longitudinal folder 100,beneath the web a, so that the two webs will be associated and foldedtogether in pass ing over-the folder 100 and between the rolls 81 82.The subsequent operations will be the same as already described, exceptthat all of the sheets will pass over the folder 106 of the finalfolding mechanism. The successive operations upon the product will bethe same as shown in Figs. 11, 13, and 15, except that the product willconsist of two sheets associated together instead of a single sheet. Inthis case, of course, the sheets will not be associated together inpairs, as they pass to the fly 108.

If it should be desired to deliver a product consisting of one fullsheet folded once transversely and once longitudinally,the frame 109,carrying the primary folding mechanism,will be shifted by means of thescrew 75, so as to bring the folders 100 101 to the position shown inFigs. 2, 4, and 5, and indicated in the diagram Fig. 9. The webs a a,will be led around the turning-bars 00 '91, rolls 92 88 and 93 89, andover the folders 100 101, and between the rolls 81 82, so as to befolded longitudinally, the same as already described. From the rolls 8182 they will be led. between the cutting and folding cylinders 102 103,where they will be severed into sheets, as indicated in Figs. 11 and 12,and folded transversely and directed between the guides 21 22, the sameas already described, and as indicated in Figs. 13 and 14. From theguides 21 22 the sheets, now folded once longitudinally and oncetransversely, will be taken by the tapes 2 4 6 and 3 5 7, the same asalready described, and carried upward to the pulleys 24, and downwardover the folders 106 107, and between the rolls 71 72 and 69 70. It willbe observed, however, that when the folders 100 101 have been shifted,as stated, the webs will be directed onto the cylinder 102 in suchposition lengthwise of the cylinder that instead of passing to thefolders 106 107,with their center lines directly over thepoints of thefolders, they will pass to these folders in such position, as shown inFig. 2, and indicated in Fig. 9, that one of their edges will passdirectly over the points of the fold ers,thus causing the sheets,instead of being folded longitudinally in passing over the folders, tobe simply carried or directed around the longer of the turning edges ofthe folders, asindicated in Fig. 9, so as to be merely directed betweenthe rolls 71 72 and 69 7 0,without being folded, thus omitting thesecond of the longitudinal folds, and causing the sheets to pass intothe control of the tapes 2 4 and 3 5, folded to the dimensions indicatedin Figs. 17 and 18. From the tapes 2 land 3 5 the sheets will pass intothe control of the tapes 2 5, and be associated together in pairs anddelivered to the fly 108, and deposited upon the tapes 51, the same asalready described, and as indicated in Fig. 8.

If it should be desired to deliver a product consisting of two fullsheets folded to the (it mensions justdescribed, the web a, after beingled around the turning-bar 91, will be led over the roll 68, and ontothe folder 100 beneath the web a, so as to be associated therewith, thesame as already described, after which the further operations ofsevering the associated webs into sheets, and folding and delivering thesheets,will be the same as just described, except that all of thesheets'will pass around the longer of the turning edges of the folder106, the folder 107 being idle.

If it should be desired to capacitate a delivery mechanism of thischaracter to deliver a product of a volume greater than two full sheetsassociated and folded together, as de scribed, it may readily be done byequipping the cylinders 102 103, in the manner shown in my applicationfor Letters Patent filed J anuary 13, 1882, No. 50,017, so that whendesired two or more pairs of sheets may be associated together, andfolded between the rolls 104c 105, or the same result could be readilyaccomplished by interposing any of the well-known longitudinal folder.In such' case a product forms of sheet-associating mechanism between therolls 81 82 and the cylinder 102, in which case the cuttingcylinder 103will be dispensed with, and suitable severing mechanism provided forsevering the webs into sheets before they arrive at the associatingmechanism. In either of these cases the sheet associating mechanismwould be rendered inoperative whenever a product consisting of one ortwo.

sheets was to be produced.

A product consisting of two full sheets might be produced by leading theweb a to the folder 100 and the web a to the folder 101, the same aswhen single sheets are delivered, and then causing succeeding sheetssevered from each web to be associated in either of the ways justdescribed before they pass to the intermediate and final foldingmechanisms. It is also to be observed that it is not necessary that thecutting mechanism and the sheet associating mechanism (if the deliverymechanism is provided with a sheetassociating mechanism) should belocated so as to operate upon the webs after they have passed theprimary folding mechanism. The cutting mechanism may be located so as tosever the webs into sheets before they pass to the folders 100 101 ofthe primary folding mechanism, and the sheets so severed from the websmay be associated before they pass to the primary folding mechanism, andthis association of the sheets may be effected by associating the websand then severing them into sheets to produce a two-sheet product, or byassociating the Webs, then severing them into sheets, and thenassociating the pairs of sheets to produce a larger product, or bysevering the unassociated webs into sheets and then associating thesucceeding sheets from each web to produce a product of two or moresheets. In any of these cases the primary folding mechanism will, ofcourse, be provided with suitable taping to conduct the sheets to andover the folders 100 101 and to the intermediate folding mechanism. Themanner of arranging tapes so as to accomplish this result is well knownin the art, and therefore need not be described.

Although the primary and final folding mechanisms, as herein shown, eachconsists of two longitudinal folders, it is of course to be understoodthat these mechanisms may consist of three or more folders, (theintermediate mechanism being made of sufficient length to co-operatetherewith,) if it is desired to operate upon a web of sufficient widthto produce three or more of the narrow webs, as a a". In such case asthis a product consisting of three or more (depending upon the number ofwebs) full sheets associated and folded together may be produced byleading all of the webs to and over one of the folders of the primarymechanism, and then operating upon them in the manner already describedfor producing a product consisting of two full sheets. It is also to beunderstood that the primary and final folding mechanisms may eachconsist of only a single consisting of two or more full sheets can beproduced by associating two or more webs before they pass over thesingle folder of the ,7

primary mechanism. or by associating two or more of the succeedingsheets severed from a single web, either before or after it passes overthe folder. To produce a product consisting of a single sheet, in suchcase a web of the width of one of the webs a or a will be printed upon.

It is also to be remarked that it is not necessary that the web or websshould be led in at the side of the delivery mechanism, as shown in thepresent case. The web or webs may be led in at the end of the mechanism,if preferred. In such case one of the webs will pass directly to one ofthe folders of, the primary folding mechanism, while the other will beled around two turning bars, so as to be transferred laterally to aposition either above or below the other web, so as to be led to thesame or the other of the folders of the primary folding mechanism,according as it is desired, or not, to associate the webs, as shown inmy application for Letters Patent filed January 13, 1882, No. 50,017.

In producing newspapers it sometimes happens that it is desirable tovary the size of the product or paper within narrower limits than a fullsheet, and this can only be done by decreasing the size of the sheetprinted. It is very difficult to diminish the length of the sheet in thedirection of its travel through the machine; but it is not difficult todiminish the length of the sheet widthwise of the machine, as all thatis necessary to accomplish this is to omit one or more columns from thesides of the forms if the columns lie circumferentially of theprintingcylinders, or shorten the columns if they lie longitudinally. ofthe cylinders, and use a web of correspondingly-reduced width. hen,however, the width of the web or the sections or narrow webs into whichthe web is split is diminished, it becomes necessary, in order topresent the webs to the folders of the primary folding mechanism in suchposition that their center lines will pass directly over the points ofthe fold ers and thus cause them to be folded in the middle, to shiftthe position of the turning bars around which the webs pass. For thispurpose the bars 91 are mounted in the ad just-able frame 99, as shown.\Vhen the webs IIO a a" are of full width, as shown in Fig. 3, the

the frame 99 and bars 90 91 to the position shown by dotted lines inFig. 3, or to some intermediate position, and thus cause the webs to bepresented to the folders in such position that, although they are ofreduced width, their center lines will still pass over the points of thefolders, and they will thus be folded evenly on their centers.

If it should be desired to deliver a product consisting of half-sheetsinstead of full sheets, the mechanism will be provided with ordinaryslitters, located, preferably, at or near the points of the folders 100101, which will be so arranged that when desired they can be ih rowninto operation and split the webs a (6 upon the fold-line as they passover the folders. The half-sheets thus produced will then be foldedtransversely by the cylinder 102 and rolls 104 105, and will then passto the folders of the final folding mechanism, and be either foldedlongitudinally or pass these folders without being folded, dependingupon the position of the folders of the primary folding mechanism, afterwhich they will be delivered to the fly 108, the same as full sheets.\Vhen halfsheets are being produced, the two webs a a will preferably beled to the same folder of the primary folding mechanism, so that whenthey are split and severed into sheets and folded by the cylinder 102they will be folded together into lots of four half -sheets each, whichwill facilitate the counting of the product. \Vhen producinghalf-sheets, the primary folding mechanism will preferably be adjustedto the position shown in Figs. 2 and 5, so that the halfsheets will notbe folded in passing over the folders of the final folding mechanism.

In conclusion it is to be remarked that in many of its details thedelivery mechanism herein described may be varied greatly witlr outdeparting from the essential features of the present invention. Theintermediate severing and folding mechanisms, instead of being of theform shown, may be of any other approved form which is adapted to imparta transverse fold to the sheet; or, if it should be desired that thedelivery mechanism should impart but one or two folds, instead 'of twoor three folds to the sheets, then this intermediate mechanism may beentirely dispensed with,the longitudinallyfolded webs being led directlyfrom rolls 81 82 to the folders of the final folding mechanism, afterpassing which they will pass to a cutting mechanism, and be severed intosheets and then delivered to the piling mechanism, and in such case thefolders of the final mechanism need not be provided with tapes; or ifthe intermediate folding mechanism is omitted, the webs may be severedinto sheets between the primary and final folding mechanisms, in whichcase'the final mechanism will be provided with tapes, or they may besevered into sheets before reaching the primary mechanism, in which caseboth the primary and final mechanisms will be provided with tapes.

It is also to be remarked that the folders of the primary and finalmechanisms need not necessarily be of the form shown, but may be of anyother suitable construction for this class of iolderssuch, for example,as the other construct-ion shown in Letters Patent No. 281,619, or inthe several Letters Patent heretofore granted to me for improvements inthis class of folders; or they may be of the construction shown in myapplication for Letters Patent No. 120,116, filed February 8, 1884.

It is also to be remarked thatthe sheet laying or piling mechanism neednot be of the construction shown herein, but maybe of any other approvedformsueh, for example, as that shown in Letters Patent No. 269,021; or,if preferred, each of the folders of the final mechanism may be providedwith a separate piling mechanism, in which case the taping of thesefolders will be modified accordingly, and in any case the taping ofthese folders may be different from that shown without departing fromthe invention, the particular arrangement of the tapes shown beingadapted merely for the purpose of illustration, and because it isbelieved, all things considered, to be the best for the purpose.

It is also to be remarked that the piling mechanism will preferably beprovided with suitable means by which the sheets, as they are delivered,will be divided into lots containing some predetermined number, so thatthey can readily be delivered without the necessity of counting, andsuch counting mechanism may be of any approved construction, but willpreferably be of the form shown in my application for Letters Patentfiled October 6, 1881, No. 144,808.

From the foregoing it will be seen that the present invention does notconsist so much in improvements in the specific mechanisms of which thedelivery apparatus is composed as in the combination with saidmechanisms of means whereby one or more of them is rendered adjustable,or in the modification of the construction of some of them, by whichthey are rendered adjustable with relation to each other.

The combination oftwo folding mechanisms, arranged to act upon the webor sheet in succession, and the second of which is a longitudinalfolder, said mechanisms being adjustable with relation to each other, sothat the web or sheet may be received by the second in position to befolded thereby or in position to be simply guided by it without beingfolded, is not herein claimed, as this subjectmatter is claimed in myprior application, filed April 1'7, 188%, No. 128,238. Neither do Iherein claim the combination, with turning bars arranged to turn andassociate webs, of a longitudinal folder for folding the associated websand a web-severing mechanism, or a websevering and transverse foldingmechanism, arranged parallel with the printing-cylinders. Neither do 1herein claim the combination, with a plurality of longitudinal folders,

of web turning and associating mechanism arranged to turn a plurality ofwebs which are running side by side, so as to change their direction oftravel and bring them into line, whereby they may be led to differentfolders to be folded separately or associated. and led to the samefolder to be folded together, as these subjects-matter are claimed inanother application.

What I claim is 1. The combination oftwo longitudinal foldders, thefirst of which is adjustable, so that it can be shifted to differentpositions whereby the product delivered from it will pass to the secondin position, to be folded thereby, or in position to pass said secondfolder without being folded, all substantially as described.

2. The combination, with a folding mechanism composed of a plurality oflongitudinal folders, of a second folding mechanism composed of a likenumber of longitudinal folders, the folders of said first mechanismbeing adjustable, so that they can be shifted to different positionswhereby the product delivered from them may pass to the folders of thesecond mechanism in position to be folded thereby, or in position topass said second folders without being folded, and a web-associatingmechanism, all substantially as described.

3. The combination, with a folding mechanism composed of a plurality oflongitudinal folders mounted in a movable frame, of a second foldingmechanism composed of a like number of longitudinal folders arranged tore ceive and act upon the product after it leaves the first folders, theframe carrying the first folders being capable of such a movement thatthe product may pass to the second folders either in position to befolded thereby or in position to passsaid folders without being folded,all substantially as described.

4. The combination, with a longitudinal folder, a transverse foldingmechanism, and a srcond longitudinal folder, the three being ar-. rangedto act upon the product in the order named, and said first longitudinalfolder being adjustable, so that it can be shifted to differentpositions whereby the product delivered from it may pass to the secondlongitudinal folder in position to be folded thereby, or in position topass said second folder without being folded, all substantially asdescribed.

5. The combination, with a folding mechanism composed of a plurality oflongitudinal folders, of a second folding mechanism composed of acorresponding number of longitud inal folders, an interposed transversefolding mechanism capaeitated to receive and act upon the product of allof the folders of the first mechanism, and means whereby the folders ofthe first mechanism may be shifted in position, so that the product maybe delivered to the folders of the second longitudinal folding mechanismin position to be folded thereby or in position to pass said folderswithout being folded, all substantially as described.

6. The combination, with a longitudinal folder, of a web-turner forturning the web before it is presented to the folder, said webturnerbeing adjustable, so that webs of different widths may be properlypresented to the folder, all substantially as described.

7. The combination, with a plurality of longitudinal folders, ofaplurality of web-turners mounted in a movable frame and arranged to turnthe webs and present them to the folders, and means for adjusting theposition of the frame carrying the turners, all substantially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
